Right now, each InfluxDB target configured at the global level also requires credentials at the topmost level. Note that also credentials with SYSTEM scope appear to not work for some reason. In the case of a multi-tenant Jenkins host, since SYSTEM credentials do not work, ALL tenants can view and use each other's credentials as only GLOBAL credentials work. It would be good to have the influxDbPublisher() call take a credential at the pipeline's folder or parent folder level as input instead.
